Jeeptek78...
Thanks for the reply,,, my noise is still there and seems to have gotten worse ,,, I took a video of the noise ,, but I can't seem to post it on here ,,, my jeep dealer had my ride for one day said no abnormal noise ,, then 3 days straight trying to find it ,,, It is definitely not an easy noise to pinpoint like you stated ,,, I have to get it back into them but don't have the time to leave the vehicle with them right now (in an hvac tech). And we are super busy , my next run on call I will leave it w/ them since I won't need the car.. hopefully you will have some insight for me by then.. I wish I could somehow send you the video ...
Maybe you could message me an email address I and I will send it.
Thanks.
And good luck

I have the same issue you both describe as well. Thought I was the only one. It was present since day 1. The salesman kept telling me it was normal and just the wheels...lol! I have installed some temporary foam pieces b/w the skid plates underneath b/c when I lightly hit them with my fists, I can duplicate the noise...however it didnt help. Please keep me posted. Thank you

I don't have the steering wheel clamp mentioned in the TSB. (Just wanted to double check). So my issue is unrelated...unfortunately.

I hope this works....

video of my noise,,, (turn up vol.)

I can't get this to play on my iphone or iPad. Can you send it via email to me if I shoot you my address. Or is there another way to post it somewhere? Would like to compare the noise.

Hello everyone. I currently have a 14 Grand Cherokee with a light resonating noise in dash area (from center left area). I have contacted STAR center about this issue. I am told that there has been very few concerns on this, but the issue is the purge line under hood may be contacting the heater core tubes. This IS NOT a metallic sound, but rather a plastic type sound. The bracket sound that was mentioned earlier usually sounds like a telephone bell ringing (I'm the originator of that TSB). Anyway, I have found that this tubes (in my case) are inface touching one another. I have yet to figure a way to keep them apart. Will keep you all informed.

Could you please post a picture of the tubes, when you get a chance? Thanks

Thanks for the info ,,, I got mine back the other day, they said they found wear marks on engine cover and put inulation tape to stop vibration.... Didn't help...
Its going back on wed. I will let them know about this..

I found this myself and had bad signs of it. I put a hose of decent thickness. It did help with that part. The noise is intermittent now and less frequent. I had also went under the car and move shields and insulted area i found to make the noise during my 'tap test'. There were a bunch. It is intermittent, but still there.

Have an assistant start vehicle and put in reverse (foot on brake to keep from moving), Bring RPM up until you hear the noise (at that point hold RPM steady).Lightly press downward on the heatercore outlet at the firewall. If this is the cause, the noise will go away. In my case.....this was the cause of the noise (heater core tube vibrating against the sheet metal of the firewall).

The heater core tubes are to the left rear of the engine (behind the plenum). If you need a photo...text " heater" to (912)398-1977 and I'll send you a photo.
